uPVC Sash Windows at Trade Prices

At Colin’s Sash Windows we are all about providing our customers with high-quality windows. Our uPVC sliding sash windows are produced in the UK and are supplied nationwide and exported worldwide. Unlike many suppliers, we always give the best price possible to all customers first time – homeowners or builders. Our uPVC sash windows are excellent in terms of energy efficiency, style, and low maintenance costs. Our sash windows operate like traditional box sash windows, both the top and bottom sashes slide up and down, and, for easy cleaning, tilt inwards as standard. Since our windows come with a 10-year warranty, you don’t have to worry about your investment.


A Choice of Colours

Choose from a wide range of colours. Along with the traditional white our vertical sliding sash windows are available in any RAL colour. If you want a more natural look our woodgrain colour selection is the right choice. The foiled finishes bring windows to life with a woodgrain effect that never needs painting. You also have the option to have your windows white inside to better suit your home`s decoration and foiled on the outside. We are now offering woodgrain windows with seamless welds making the joints almost invisible.


Our sash UPVC windows can be specified with a wide arrange of additional hardware colours. There are white, gold, chrome and satin silver variations of the handles and locking mechanisms. This way you can customize your preferred window even more! The colours are carefully chosen to suit even the most fastidious customer. The special coating of the hardware is ultra durable and will last many years with even high daily usage. Additionally, you can ask us about more colour options using our online contact form.

Type of Sash Horns

As one of the key features in a uPVC sash window, the sash horns are important selection for every client. Here at Colin’s, we offer you the opportunity to select your preferred type of sash horns. There are just two of them – run-through and plant on (also known as stick on). This simple yet important feature can make your uPVC sash windows instantly recognisable. But what to choose when you are not sure how these two differ from each other? For most clients, the run-through sash horns are a natural choice, simply because of the authentic look of the windows. Without any visible extensions, the uPVC sash window looks excellent and keep its aesthetic look. On the other hand, plant on sash horns is added as a small attachment just like the picture below shows.
